Product Description

Epifanes Fiberglass Filler 1500g (3.3lb) (FFW.1500) is a fast‑drying, two‑component polyester repair filler designed for small repairs on fiberglass (GRP) above the waterline. It provides excellent adhesion on properly cleaned and degreased fiberglass and can be applied in thick layers without shrinking.

This filler is ideal for filling dents, gouges, and surface irregularities in fiberglass hulls, decks, and superstructures. It is also suitable for small repairs in one‑ and two‑component paint systems on steel or wood above the waterline.

Mix the base with 2–4% white hardener (included). Pot‑life varies from 5–10 minutes depending on temperature.

Once cured, Epifanes Fiberglass Filler sands easily and can be recoated with all Epifanes one‑ and two‑component primers and topcoats.

Package contents include 1500 grams of base material with 50 grams of hardener white.

Surface Preparation

Fiberglass (GRP): Degrease with Epifanes Fiberglass Prep Cleaner to remove wax. For rough‑side fiberglass, remove the waxy layer with Scotch‑Brite before applying filler.

Steel / Painted Surfaces: Clean, degrease, and sand to ensure proper adhesion. Suitable for small repairs in one‑ and two‑component paint systems above the waterline.

Recoating Compatibility

Primers: Epifanes Multi Marine Primer, Epifanes Epoxy HB Coat, Epifanes Epoxy Primer, Epifanes Poly‑urethane Primer
Topcoats: Epifanes Mono‑urethane Yacht Coating, Epifanes Poly‑urethane Yacht Coating

Important Application Advice

After sanding, immediately apply one thinned topcoat (15–20%) to seal the filler and prevent moisture absorption. This avoids spotting caused by humidity intake.

New polyester must be at least 14 days old and free of chemicals before applying filler.
